When they say "Jettisoned", it makes it sound like one of the flight computers decided to drop the panels. Wouldn't it more be the case that the panels are deliberately designed to be blown off? I have a hard time believing that any control system could react in time in case of an engine explosion...
Very common in Europe, yeah. I could even dare to say that it's mandatory for young men here in Switzerland, since it's impossible for conscripts to go straight from highschool to college.
I don't mean to sound negative but doesn't someone try this (browser-extension-based-multi-website-chat) every 2 years or so and the problem is they never gain enough traction, so basically every room is empty? what makes this one different?
Ask HN: Looking for some feedback for my tracking startup
I recently launched a site I'd been building for a few years in my spare time called Tracktacular, which is a collection of web apps to help organize your life (tasks, goals, dreams, recipes, etc). I'm looking for some general feedback about the site and the idea as a whole.

I should mention that I originally started working on this as a site entirely for me, but over time wondered if others might find it useful. As such I don't have any income strategies yet, this is more of trying to find out whether the idea has merit.

Thanks for your advice.

The question you should be asking yourself is, why did patio11 make A/Bingo available as open source.

Clues:

1. It's called A/Bingo

2. It's hosted on his bingo card creator site, not on github or kalzumeus.com (his personal site)

3. People tend to link to interesting open source projects

4. The text they use in the link is usually the title of the project

5. Google uses the number of links and the link text to rank sites on keywords

This is what he means by using his coding skill against his competition in ways orthogonal to programming.

I would expect similar effects from learning diff eq's or haskell and maybe from challenging sports like rock climbing, paragliding, or maybe Ashtanga yoga.
Two thoughts here.
1) You're working from an awfully small sample, especially for a component that is supposed to be of such a high reliability. Then again, look at the probabilistic assessment of Shuttle success vs. actual.
2) The Merlin 1C engine is only going to make a few more flights afaik. Starting some time in 2013 they'll be switching to Merlin 1D.
It's interesting to compare that MTBF with the fact that there are about ten million airliner flights per year in the US. If we arbitrarily assume that the average airliner flight is two hours, that's a substantial number of failed engines per year, so obviously the redundancy on these craft really does work.

Incidentally, I went searching for airliner engine MTBF statistics and your comment was already near the top of Google's results.

Edit: erroneously said five million flights per year because I was looking at 2012 statistics for only the first six months. of the year. Oops.

I've actually considered getting into aerospace software development. It sounds awesome --- after all, you're writing software for devices that leave the planet! --- but what's given me pause is that the software creation process itself is so necessarily conservative that I'm afraid the process would strip all the joy out of the actual coding.
Haven't tried fully but looks good!
What is the variance of your estimate?
The H-bomb uses a fission A-bomb to get enough temperature and pressure to produce the fusion reactions.

The sun is a 100% fusion reactor.

If you mix a fusion and a fission reactor, probably you will have most of the disadvantages of the fusion reactors; in particular you will have a lot of long-living radioactive byproduct of the fission reactions.
The main problem with building a custom ROM for the G2x is that NVIDIA will not release the Tegra2 GPU drivers to the community. So unless LG releases an official ICS version, there is no way for third party devs to get their hands on the custom driver. There are already ICS custom ROMs without GPU graphics acceleration for the G2x, and they don't work well. For example, when trying to use the browser, the screen will flicker and sometimes go black.
This is probably the first time I have heard of OrientDB being used in production. It seemed like a unique database but it wasn't backed by a big commercial entity. It is used as the main datastore and the edges cache this data?
Absolutely! I can look back at the set of tutorials that I myself wrote while I was learning JavaScript and HTML5, and there's a bunch of stuff that makes me blush now - including among other things using jQuery and this quote: "Learn jQuery and love it." For the sake of completeness (and cannon fodder for anyone who wants to criticize) it's here: http://www.iguanademos.com/Jare/docs/html5/Lessons/

My concern was perhaps due to expectations about the quality of the site's content, as people were talking about where it stood compared to w3schools and even MDN.

Digg's redesign is especially bewildering. I double checked. On 1920x1200, I see exactly 6 headlines. On reddit, I get 16 (with photos!).

Not only are the (mostly useless) images unnecessarily huge, but the layout is fixed. Masonry, out of the box, uses the entire screen real estate.
You're talking about two very different things during two very different times.

9/11 was an event witnessed by the public on a massive scale. This was a private development only witnessed by those who needed to know.

You didn't have the internet in 1950s, so even if somebody did know about it and told their friend or grandchild, would that person have found it interesting enough to tell more people.

Lastly, is the attempt to make a UFO really a conspiracy?? It didn't work, so there is very little to report.
The Falcon 9 v1.1 will switch to an 8 engines circle with another in the middle layout (as well as using the more powerful Merlin 1D engines). The v1.1 is expected to replace the current v1.0 next year.

Slight nitpick: higher MPG does not necessarily mean less emissions per mile; car engines do differ in the amount of emissions they produce per gallon of gas consumed.

For example, adding a catalytic converter to a car may decrease both MPG and emissions (http://en.wikipedia.org/wiki/Catalytic_converter#Environment...), so removing it may increase both MPG and emissions. And that is even disregarding the fact that adding that converter increases the weight of the car.

I'm pretty happy to share this; its based on a JSON validator I've been using for a long time. I reimplemented the technique in Python 3 for use with function annotations. Its inspired by Typescript; my ambition would be that its syntax is widely adopted and eventually static type checkers support it and IDEs can do auto-complete ala Typescript.

Right now its a useful little runtime checker for you.

Ask PG & HN: So, when should someone go to Silicon Valley?
I once asked this "Ask HN: You arrived at Silicon Valley. What do you do next?" (http://news.ycombinator.com/item?id=4268060)

The few responses I had basically said "DON'T COME TO SILICON VALLEY UNTIL YOUR READY WITH AN IDEA AND SO FORTH AND MONEY TO SUPPORT YOURSELF" or something like that.

While nice and all, this seems contradictory to the advice that people like PG and various blogs say that you need to be in an environment like SV so that non motivated people commonly found elsewhere don't spend all day shooting your dreams and ambitions down.

Which comes to the question. When should someone come to Silicon Valley? Can a dream survive in one of the most expensive places in the world to live when all you have is a dream and no other resources?
Yeah, you should try that in IE 10. Probably looks much more different than Webkit and Mozilla.
I think the important distinction is that banks will not open accounts without reasonable documentation of identity.

So, even if banks and paypal freeze accounts for the exact same reasons, paypal will do it much more, because they have less confidence in the identity of the account owner.
To those who haven't, I wholeheartedly recommend learning another language. I think it's one of the most important things you can do for your mind—I believe it truly changes the way you think on a fundamental level.

Sometimes, when I tell people this, they argue that they're "too old" to learn a new language. When they do, I tell them the following story.

I was in Berlin this March, and I met a Belgian who spoke 6 or 7 languages fluently (as many Belgians apparently do). I was currently on "vacation" from a semester abroad in Italy, where I was taking an intro Italian class and really enjoying it so far. I mentioned this to the Belgian, but I expressed my concern that I was too old to become fluent:

"You can't learn new languages properly once you're my age."

He scoffed. "Sure you can. You just have to open your mind!"

That line stuck with me. Now, it may or may not be true that your brain can't fully "accept" new languages past a certain stage in your development, but that's not the point. The point is that I believed that I couldn't, and that belief was actively discouraging my progress. So I followed the Belgian's advice: I stopped telling myself I was too old, I went out of my way to speak the language, and I pushed myself harder to become conversational. By the end of the semester, I'd achieved that. (I'm by no means fluent, but I'd like to live there again soon with fluency as a goal.)

I do wish that I'd started earlier, because I've uncovered a real passion and knack for languages that I didn't know I'd had. But—perhaps contrary to popular belief—it's never too late to start.

(As an aside, I found it interesting that after just three months, I spoke Italian better than I spoke German after three years of high school classes. I attribute this partly to actually living in Italy, but also to a broken language learning system in our public education. But that may be a comment for another day.)
I think thrust counts to a degree, as you'll lose velocity from gravity drag if the time to orbit is too high. The degenerate case would be if your thrust is less than the weight of your rocket (i.e. not moving).
In fusion-based nuclear weapons, a fission bomb is used to create the temperature and pressure needed to kick off nuclear fusion. Calling that "combined fusion/fission" is like calling my car an electric hybrid because it uses an electric starter.

Detonating a nuclear weapon inside of a power plant isn't really practical. :-) Existing nuclear power plants don't get anywhere near the temperature and pressure needed to start nuclear fusion.

So, now we have the engineers trying all sorts of ways to get to the needed temperature and pressure without turning the plant into a smoking crater. That's where all the fancy lasers and magnetic pulses described in the article come in: They're trying to aim the heat source so they can superheat the fuel without melting the containment vessel.
Gap years are awesome - especially if you travel.

As a parent, I hope to instill the following to my two daughters:

Take a gap year or two (at most)
Do not get married earlier than 25
Do not have kids earlier than 30

You really really need to enjoy a gap year and enjoy your 20s, but do so in a way that sets you up to be comfortable and happy for the rest of your life.
OK, so by mentioning 'outsourcing' we start to understand a bit more. You're focused on enterprise (or reasonable sized operations then?). Then you should say so.

You have to remove all the jargon from your pages (and preferably simplify the text by removing a lot of it) and then explain your proposition like it was to a 5 year old (as someone else said here).

Sorry to go on about this, but it's crucial if you're going to market your product successfully.

Try this:
You are in an elevator, you've got 3 minutes between floors to make your grandmother understand what you do and why people should use your service. What would you say? :)
I took a gap year and joined the Americorps NCCC. I spent the year volunteering all across the Southern states and served with people ages 18-24 from across the country on construction and education projects. It was a great way to expand my limited understanding of the world and gain confidence. Had I gone straight to college I would have missed out on a lot of learning. I think gap years are a great idea but recommend doing something interesting, productive or useful for yourself or others.
Brain connectivity predicts reading skills

If its title swapped 'Programmer Competency Matrix' with 'Computer Science Competency Matrix' it would make a lot more sense. Some of the level 3 competency ratings have little relevance in the real world.

Everyone in the programming world knows programmers (often intelligent, educated, and experienced ones) get caught up in silly details of perfecting their code and are completely unproductive without an experienced manager (or tutor) guiding them. I can't help but laugh when a bushy tailed non-programmer steps in, and produces something quickly and effectively using seemly simple tools.

Show HN: Apple Security Issue Allows Logins With Old Emails
I switched my Apple ID email to another address today, but I accidentally used my old email address and saw I was able to log in.

Why do they do this? Isn't it a potential security issue?

I use a email provider that releases emails back into the pool once they expire. Anyone else picking up my email could reset my password.

Update: Reset email came to my old email, clicked the link and it showed "Enter a new password for <new_email_here> below". I'm guessing it works.

Update 2: Disclosed issue with product-security@apple.com.
They said "ejected", not "jettisoned". You can be 'ejected' from a vehicle if you're not wearing your seatbelt, so the word doesn't require active response.
Are failures independent?
B-trees are great! They have better locality than binary trees --- that's why filesystems are universally based on B-trees: seeks are slow. As cache effects become ever more important, B-trees are starting to become important even for problems that fit in main memory.
I think the argument isn't necessarily that no operation of that size could be kept secret, but rather one which involves killing thousands of innocent people would almost certainly have people deciding not to keep the thing a secret.

With something like this, it's likely that everybody involved saw their participation as a good thing, and saw no reason to break secrecy.
Interesting. If you remove all your personal information from the account, theoretically it's a shell account that isn't tied to you in any way. So in essence, you've deleted your account.

But what about history? What about all the actions you did before you "deleted" your account? Are those still preserved?

Regardless, this brings up an important question: should online services be required to let you 110% erase any presence you had on their property?

That's seemingly the purpose of most temporary freezes. They ask for identification and a description of what you're selling with the account, and if the response is satisfactory, unfreeze the account.

Banks do their underwriting up front, PayPal delays it until some kind of event triggers it (whether it's a spike in processing volume, a change in average ticket size, or buyer complaints). Since we only read about an incident or two a month, most people probably never hit one of those triggers, only using their accounts for eBay purchases and the like.

When an account starts looking risky, or starts looking like a real business, they get treated like one -- the sudden need for documentation is the jarring part, and the sudden loss of the account if underwriting doesn't approve of the business the cause of the dissatisfaction.

I'd bet the whole process could be made a lot less antagonistic with just a change to wording -- better explanation of what's going on, why PayPal wants the documents now that they didn't ask for before, and the fact that a temporary freeze doesn't mean you're losing your funds or won't be able to continue processing.
One factor that I don't think has been answered, if this engine shutdown was going to be the 3rd and would cause a mission loss, could if have been persisted with.

It isn't clear whether it was on the way to complete engine failure or it was shut down to play it safe.

Walmart has a monopoly on items you can buy at the checkout counters inside of their stores.

It's looking really good. Sandia ran simulations, found a sweet spot, and recently ran a test in which they magnetically crushed a liner without fuel. That test worked out exactly how the simulations predicted.

They have several other tests to do and plan to do a complete test by the end of 2013. If it still works the way their simulation predicts, they'll approximately hit breakeven.

The next step will be to build a machine several times bigger. According to the sim, that would take us from breakeven to a 100x to 1000x energy gain (depending on how powerful they make the machine.)

Such a large gain helps a lot for turning it into a practical plant. For one thing, they'd only have to fire a shot every ten seconds or so. NIF's laser approach, by comparison, would require ten shots per second.
following the Engine-1 failure, did Falcon 9 continue w/ six engines operating, or was one of the two previously shutdown engines re-engaged?

Yep! Restart Fund is actually partially a product of our pivot. We basically weren't getting anywhere with micropayments, and we weren't sure where to go next. We got approached by a few big companies about talent acquisitions, but we knew we really wanted to be working on something early-stage with a lot of opportunity for growth. So hopefully if anyone else is in a similar position, Restart Fund could be another option to consider.
The panels may have been designed to jettison once they reached a certain pressure differential, or they may be jettisonned by computer.

How quickly do engines explode? Is it faster than 2 cars colliding? Computers deploy air bags quickly because electricity travels faster along wires in your car chassis than the car travels into something else.

Visualize a bumper with sensors - as the bumper is deformed by a collision, a sensor shifts an electron in the copper wire, and the electron next to it shifts. There's a cascade of shifting electrons along the wire, and it races backwards through the car's body, chased by the destruction of the car as it collides with another object. The cascade of electrons hits the air bag computer, which begins another cascade of electrons to the air bag. The wave of destruction has covered most of the distance to your windshield by now. The air bag deploys as molecules of air rush from their high-pressure canister to fill it. As the bag hits its most pressurized point, your car is coming to a stop as its kinetic energy is combined with energy from the other object.
Stuff White People Like

#120 Taking a Year Off

When someone goes through a stressful experience they usually require some time off to clear their head, regain focus, and recover from the pain and suffering. Of course, in white culture these experiences are most often defined as finishing high school, making it through three years of college, or working for eleven months straight with only two weeks vacation and every statutory holiday (“they don’t count because I had to spend them with family.”)

Though you might consider finishing school or having a good job to be “accomplishments” many white people view them as burdens. As such, they can only handle them for so long before they start talking about their need to “take a year off” to travel, volunteer, or work abroad.

I land solidly in the right-hand column, particularly on the systems programming front: I've made major contributions to the NT kernel. I'm not sure this matrix has all that much significance: Google rejected me after the in-person interview: do they want people who can sort N items in O(1) time, work 30 hours per day, and create new scripting languages over lunch?
